SCHKLQ

Purpose:

    !>
    !> SCHKLQ tests SGELQF, SORGLQ and SORMLQ.
    !>

Parameters
    DOTYPE

    !>          DOTYPE is LOGICAL array, dimension (NTYPES)
    !>          The matrix types to be used for testing.  Matrices of type j
    !>          (for 1 <= j <= NTYPES) are used for testing if DOTYPE(j) =
    !>          .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used.
    !>

    NM

    !>          NM is INTEGER
    !>          The number of values of M contained in the vector MVAL.
    !>

    MVAL

    !>          MVAL is INTEGER array, dimension (NM)
    !>          The values of the matrix row dimension M.
    !>

    NN

    !>          NN is INTEGER
    !>          The number of values of N contained in the vector NVAL.
    !>

    NVAL

    !>          NVAL is INTEGER array, dimension (NN)
    !>          The values of the matrix column dimension N.
    !>

    NNB

    !>          NNB is INTEGER
    !>          The number of values of NB and NX contained in the
    !>          vectors NBVAL and NXVAL.  The blocking parameters are used

    !>

    THRESH

    !>          THRESH is REAL
    !>          The threshold value for the test ratios.  A result is
    !>          included in the output file if RESULT >= THRESH.  To have
    !>          every test ratio printed, use THRESH = 0.
    !>

    TSTERR

    !>          TSTERR is LOGICAL
    !>          Flag that indicates whether error exits are to be tested.
    !>

    NMAX

    !>          NMAX is INTEGER
    !>          The maximum value permitted for M or N, used in dimensioning
    !>          the work arrays.
    !>
